Pixel alignment for binocular display systems

Abstract

According to an aspect, a system includes a first image source for a left eye and a second image source for a right eye. The system further includes at least one window in a first optical path for the first image source or a second optical path for the second image source, the at least one window configured to align first pixels from the first image source with second pixels from the second image source.

         1 . A system comprising:
 a first image source for a left eye;   a second image source for a right eye; and   at least one window in a first optical path for the first image source or a second optical path for the second image source, the at least one window configured to align first pixels from the first image source with second pixels from the second image source as part of a binocular display.   
     
     
         2 . The system of  claim 1 , wherein the at least one window is configured at an angle relative to the first optical path or the second optical path. 
     
     
         3 . The system of  claim 1 , wherein the at least one window comprises at least one first window in the first optical path for the first image source and at least one second window in the second optical path for the second image source. 
     
     
         4 . The system of  claim 3 , wherein the at least one first window is configured at a first angle relative to the first optical path and wherein the at least one second window is configured at a second angle relative to the second optical path. 
     
     
         5 . The system of  claim 1 , wherein the at least one window comprises a first window and a second window, wherein the first window aligns the first pixels with the second pixels horizontally, and wherein the second window aligns the first pixels with the second pixels vertically. 
     
     
         6 . The system of  claim 1 , wherein the at least one window comprises borosilicate crown glass. 
     
     
         7 . The system of  claim 1 , wherein the first image source comprises a first light emitting diode panel, and wherein the second image source comprises a second light emitting diode panel. 
     
     
         8 . The system of  claim 1  further comprising:
 at least one processor operatively coupled to the first image source and the second image source. 
 
     
     
         9 . The system of  claim 1  further comprising:
 a first lens in the first optical path; and 
 a second lens in the second optical path. 
 
     
     
         10 . The system of  claim 1 , wherein the system comprises a head-mounted device. 
     
     
         11 . A method comprising:
 identifying an error in alignment between a first image source and a second image source, the first image source and the second image source configured to provide a binocular display on a computing device;   determining at least one angle for at least one window in a first optical path for the first image source or a second optical path for the second image source to correct the error; and   configuring the at least one window on the computing device with the at least one angle.   
     
     
         12 . The method of  claim 11 , wherein the error comprises pixel alignment. 
     
     
         13 . The method of  claim 11 , wherein the at least one window comprises a first window and a second window, and wherein determining the at least one angle for the at least one window in the first optical path for the first image source or the second optical path for the second image source comprises:
 determining a first angle for the first window in the first optical path and a second angle for the second window in the second optical path.   
     
     
         14 . The method of  claim 13 , wherein the error comprises a vertical error and a horizontal error, wherein the first angle corrects the vertical error, and wherein the second angle corrects the horizontal error. 
     
     
         15 . The method of  claim 11 , wherein at least one window comprises borosilicate crown glass. 
     
     
         16 . The method of  claim 11 , wherein the first image source comprises a first light emitting diode panel, and wherein the second image source comprises a second light emitting diode panel. 
     
     
         17 . The method of  claim 11 , wherein configuring the at least one window on the computing device with the at least one angle comprises causing an actuator to move the at least one window to the at least one angle. 
     
     
         18 . A computer-readable storage medium having program instructions stored thereon that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
 identifying an error in alignment between a first image source and a second image source, the first image source and second image source configured to provide a binocular display on a computing device;   determining at least one angle for at least one window in a first optical path for the first image source or a second optical path for the second image source to correct the error; and   configuring the at least one window on the computing device with the at least one angle.   
     
     
         19 . The computer-readable storage medium of  claim 18 , wherein the at least one window comprises a first window and a second window, and wherein determining the at least one angle for the at least one window in the first optical path for the first image source or the second optical path for the second image source comprises:
